NaCl(s) is insulator, silicon is semiconductor, silver is conductor, quartz is piezo electric crystal

Frenkel defect is favoured in those ionic compounds in which sizes of cation and anions are almost equal

$$FeO_{0.98}$$ has non stoichiometric metal deficiency defect

Density decreases in case of crystals with Schottky's defect

Enzymes catalyse mainly bio-chemical reactions

Coenzymes increase the catalytic activity of enzyme

Catalyst does not initiate any reaction

The value of equilibrium constant is changed in the presence of a catalyst in the reaction at equilibrium

$$E_1 > E_2$$

$$E_2 = 0 \neq E_1$$

$$E_1 = E_2$$

$$E_1 < E_2$$

Electrophiles are generally neutral species and can form a bond by accepting a pair of electrons from a nucleophile

Electrophile can be either neutral or positively charged species and can form a bond by accepting a pair of electrons from a nucleophile

Electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from a nucleophile

Electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from another electrophile
